To all w from it' may 'concern Be it lrnovvn that I, Can; QUERER, acitizen of the United States of funerica, and resident of" Cooper Township'. 1Webster 5 County, 1owa,'have invented a neufv and useful Journal Bearing, of which the following is a specification. l

The object of this invention is to provide an improved construction for a journal bearing.

A further object of this invention is to provide an improved construction for a journal bearing: adaptedl to bemounted forl s reciprocation. 4 A further object of this invention is vto provide an improved construction for a journal bearing adapted to belmounted for reciprocation, spring-held in one direction `and guided in its reciprocation.

A further object of this invention is to provide an improved construction for a journal bearing adapted to be mounted for r`eciprocation and guided in its reciprocation.

A further object of this invention is to provide an improved construction for a journal bearing adapted to be arranged in pairs, one of which is fixed and the other adapted for reciprocation, guided in its reciprocation andfspring-held in one direction.

arrangement and combination of elements hereinafter set forth, pointed out in my claim and illustrated by the accompanying drawing, in Which- Figure 1 is a perspective of one of a .pair of journal bearings. Figure 2 is a perspective of the other of a pair of journal bearings. Figure 3 is a cross-section illustrating the journal bearings mounted in'pairs, means for reciprocating one bearing of each pair, means for guiding the reciproca-ble bearing, and means for spring-pressing the reciprocable bearing toward the other in each pair.

This invention relates to and is divided' out of my application for Letters Patent of the United States Number 380,544, led May 11, 1920.

In the construction and mounting of the devices as shown the numeral 10 designates one of a pair of supports (the other not being shown) adapted to be mounted in parallel relation and spaced apart. Primarily the supports 10 are parts of the frame of a corn husking machine and the bearings here- My invention consists in the construction, j

inafter described are used for rotatableV mounting of end portions .of husking rollers; but the same journal bearing and general 'arrangement of parts may be utilized indifferent structures and do not desire to be understood aslimiting myself to the precise use herein set forth and illustrated and described in my parent application above referred to.

A base bar 11 is arrangedtransversely of, fixed to and connects the supports 10 and a cap bar 12 is arranged transversely of, fixed to and connects the Asupports 10 above, parallel withVv andv spaced from the base bar 11. A plurality of journal bearings are mounted between the base bar 11 and cap bar 12, resting on the former and conned by the latter against vertical movement, and said bearings preferably are arranged in pairs in such locations. The journal bearings are alike in form, size and construction and are 'usable interchangeably save and except that the bearings of each pair preferably are right and left respectively because of a peculiarity of construction hereinafter pointed out, which contributes to stability of mounting. The right and left journal bearings (Figures 2 and 1) are designated generally by the numerals 13, 14:. Each bearing 13 or 1&1- vis formed of a single pierce of metal preferably by molding or casting and is of a Width slightly greater than that of the -base bar 11, a flange 15 being formed on one edge and adapted to overlap and engage a side margin of said'base bar. lt is the function of the iiange 15 to guide a movable bearing block in reciprocation relative to the base bar 11 and prevent twisting of said block on said bar. Therefore, one of the blocks 13, 14 has the flange on one bottom edge thereof While the other of said blocks has the flange on the opposite bottom edge thereof and, when the two blocks are mounted in juxtaposition on the bar 11 said flanges are in alinement and Contact With the same side margin of said bar. Each of the bearing blocks 13, 14 is formed with a centrally located horizontal hole 16 adapted to receive and journal a shaft 17. Each of the bearing blocks 13, 14 is formed also with transverse grooves 18, 19 in its upper and lower face respectively. The grooves 18, 19 are in the same vertical plane and are on opposite sides of and extend at right angles to the hole 16. Adjusting bolts 20, 21 are mounted tor rotation in the supports'l() between the bars 11, 12 and extend loosely through the grooves 18, 19 respectively ot successive bearing blocks arranged between said bars. The adjusting bolts 20, 2'1 have some influence and efect in guidingand holding movable bearing blocks between the bars. The bearing' blocks 13, 14 also are ormed with vertical bolt holes 22, 23 extendingtherethrough on opposite sides of and at right angles to the grooves 18, 19 and there being no bolts in the holes 22, 23 thereof. Each of the bearing` blocks 13, '111 also is formed with depressions, cavities or seats 25, 26 in opposite vertical faces between end portions of the grooves 18, 19 and extending as to depth parallel with said Agrooves. Bar washers 27 are threaded on the adjusting bolts 20, 21 and extend between them. The

bar washers 2T also are contained betweenand independent of the bars 11, 12. The bar washers also are contained Abetween a movable bearing block 14 ot one pair and a iixed bearing' block 13 ot another pair and an expansive coil spring' 28 is interposed between each of the movable bearing blocks and an adjacent washer and impinges at its ends thereon one end aortion ot each s rinOf being received in a seat'or depression 25` 26 for location thereof relative to the` bearing block. It will be understood that the bearing blocks 13, 14 may be selectively employed and the springs may be selectively applied to them and also selectively applied to opposite sides thereof. For instance, the bearing blocksl may be mounted as shown or they may be mounted in reversed relative positions. l/Vhen assembled as shown the iixed bearing blocks support the shafts journaled therein in stationary positions and the movable bearing,- blocks support the shaftsV journaled therein in movable relation to the` other shafts, thus providing' means 'for automatic separation of the shafts under yielding pressure of the springs backing the movable blocks, under the strain ot a load tending to separate the shafts ot a pair.

I claim as my invention-v The combination with a suitable support, parallel bars carried by said support and threaded rods loosely mounted in said support and extending between and parallel with said bars, of a plurality of bearing members mounted side by side between said bars, some of said members being lixed, the others being movable in the same plane therewith, each bearingmember being formed with grooves adapted to receive said rods loosely, and also formed with springend seats, bar washers formed with screwseats threadingr on said rods, each washer being'` located between a movable and a fixed bearing member and spaced from both and adapted to be adjusted by said rods to and fro relative to said fixed member, and eX- pansive coil springs interposed between and impinging at oppositev ends on the washers and movable members, one end of each of said springs entering one of said seats.
